FOLDING CHAIR.

Application led November 18, 1921. Serial No. 516,095.

T aal! whom t may cof/wem:

. Be it known that I, BERNHARD M. BnsKow, a citizen of the UnitedStates, residing at Miami'Beach, in the county of Dade and State ofFlorida, have invented or discovered certain new and useful Improvementsin Folding Chairs, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to legless folding chairs and has' for itsobject-to provide a simple and convenient device of this kind which ismore especially adapted to be removably attached to a plain board seatsuch as is used in the bleachers of base ball parks or in other placeswhere cheap seating stands are provided for the accommodation of largenumbers of persons. To this end the improved folding chair preferablycomprises a light sheet metal seat frame to which is hinged a foldingbac-k rest, the seat frame having depending members, to embrace a boardon which the seat will rest when in use,one set, at least, 0f thesedepending members being preferably of elastic spring metal so astoafford a frictional hold on the edges of the board on which the seat isto be placed, thus removably securing theI folding chair to the boa-rd,all as will hereinafter more fully appear.

In the accompanying vdrawing Fig. 1 is a plan View of the frame of theimproved folding chair with the back in raised position, and Fig. 2 is aside View of the same a board to which the chair may be removablysecured being denoted by dotted lines. Fig.` 3 is a detail bottom viewof the front portion of the seat frame, showing the spring arms andtheir mountings. Fig. 4 is a detail sectional view on line 4 4, Fig. 3.-Fig. 5 is a sectional view of the chair in folded condition. Figs'. 6and 7 illustrate a modification.

Referring to the drawings, 1 2 denotes the side partsof the seat frameand 13 the front part thereof, said front part being shown integral withsaid side parts, but itmay be a separate piece secured to the sideparts. The rearends of the side parts, 12 are twisted approximately 90"Vand bent down forming ears 15, and to these depending ears the back 16is suitably pivoted, as by rivets 17. The 'rear portions of the sideparts 12 are connected together by a cross bar 18. Secured to the frontpart 13 and to the top of the back 16 are tapes 19, preferably of steel,

bar or part 13 by means of looped brackets 22 secured to said bar orpart, said brackets affording bearings in which said arms are journalledso that partial rotation of said arms in said bearings is permitted. Tosecure said arms in said brackets, while permitting limited rotarymovements thereof, said arms are provided with pins 23 received in slots24 in the-brackets 22, the end walls of said slots, when engaged by saidpins, serving as stops to limit the turning movements of said arms.

When the chair is folded for convenient transportation the fingers 21are turned over close to the bar or part 13, as shown in full lines inFigs.V 3 and 5, but when the chair is in use the said fingers are turnedto the position shown in full lines in -F igs. 2 and 4, and will thenserve, in c0-operation with the rigid, depending ears 15, as grippingmembers to engage a board, as w, to removably attach said cha-ir to theboard. In this gripping operation the spring arms 20 may yield,.asdenoted by dotted lines in Fig. 3, so as to have a. strong butelastic hold on the board as also adapting the chair to be attached toboards of different widths.

Attached tothe front seat part 13 and the top of the back 16 is a cover25 of leather, canvas or other suitable flexible material, said coverbeing partially supported by the tapes 19, t-hus affording a comfortableseat for the' user. The tapes 19 are preferably of steel and serve notonly to support the flexible cover 25, but,.primarily, as a mosteffective means for bracing the back 16 Without in any way obstructingthe seat proper, so that the cha-irs may be placed. as close together asmay be desirable and thusthe seating capacity of the boards on which thechairs are supported will not be lessened or interfered with. Thisfeature of bracing the pivoted or folding back of a chair by Hexiblemeans connecting the seat portion of the chair tothe upper part of apivoted or foldl ing back may, of course, be applied to chairs otherthan legless chairs, as will be obvious. In order, however, that theflexible means or tapes may properly brace the folding back 16 and mayproperly co-operate with the seat portion of the chair, it is aaeaevanecessary that the rear cross bar 18, beneath which said fiexible meansor tapes extend. should be at said seat ortion and should be locatedforward of tie pivotal point of the said folding back, as clearly shownin Figs. l and 2.

Instead of the spring arms 20 for remo-v'- ably attaching the chair toboards of" different widths other equivalent means may be employed. Forexample, the' chair seat might be provided on its lower lsidewithsliding` spring-retracted hooks, as 26, the inward movements of which,under the inuence of springs, as 27, encircling the Shanks 28 of thehooks, being limited by fixed stops, as 29. See Figs. 6 and 7. Thecollar 30, attached to the shank 28 and between which and one of thesupporting lugs 31 thespring 27 is located, may be formed with a flattop' sliding in contact'with the y frame part 12, 'sa-id flat toppreventing the rod 27 from turning.

From the foregoing it will be understood that the invention provides a.simple and convenient legless chair adapted to be removably attached toa board of an otherwise uncomfortable stand, and which chair may befolded for convenient transportation.

The invention is not to be understood as being limited to the detailsherein shown, as

these details may be varied widely, within v the province of mechanicalskill, Without departing from the scope of the invention as definedbythe following claims.

Having thus described m 1 invention I cla-im and desire to secure bytters Patent:

l. A folding legless chair composed of a seat portion and a back pivotedthereto, said seat portion being provided with means for removablyattaching the chair to a board on 2. A legless foldingl chair comprisinga..

sheet metal seat frame part with rigid depending ears at its rearportion and a cross bar near the rear of said seat frame partfa backpivoted to said ears, spring arms mounted at the front of said seatframe part, ytapes extendin from the front of said seat frame part anbeneath Said cross-bar to the top of said back, and serving to brace thelatte-r, and a flexible cover partially supported b said tapes.

3. A chair comprising a pivoted or folding backycombined with a seatportion comprising a rear cross bar located forward of the pivotal pointof said back, and flexible means extending from the forward part of thechair seat and beneath said rear cross bar to the upper part of saidback, and thus serving to brace the said back when in an operativeposition.

4. A chair comprising a pivoted or folding back and a seat portioncomprising side members and front and rear cross-bars, said rearcross-bar of said seat portion being located forward of the pivotalpoint of said back, combined with fiexible members extending from saidfront cross-bar and bcneath said rear cross-bar to the upper part ofsaid back and thus serving to brace thel said back when in an operativeposition.

I n testimony whereof affix my signature.

BERNHARD M. BESI'OW.
